I bought this modem 2 weeks ago and despite about a dozen attempts to install it, have been unable to make it work under windows 2000 pro, which is a real surprise as this should be easy. Plug and play does see it at first and attempts to install the drivers but the first 8 or 9 times that they installed, they clearly didn't install correctly as although Device Manager listed the modem as being there, any attempt to query it resulted in an instant black screen and a reboot of the PC. Eventually after much muffled swearing and at least 2 re-service-pack installations (it needs a minimum of SP3 by the way) I managed to get this modem to finally install and on the right COM port too. It'll dial out as well, but then I find that it randomly causes my PC to reboot when in use - it can happen at any time without warning and gives you no entries in the event viewer to help out either - the longest it's stayed online for so far is 10 minutes which is no use to man nor beast. I've heard that it works fine under XP but under 2000 it's pants - I wouldn't recommend it to my worst enemy. I must say that the creative labs tech support guys have tried to be helpful, but they haven't come up with anything that I haven't already tried, including installing it on a second PC, so this one is on it's way back for a refund, Mr Amazon. Can you make sure you put a public health warning on it while you at it? Ta very much.
